Something like Fedora which releases newer code quicker will provide a better desktop/laptop experience. It’s the same reason other stable distros, like the EL distros, aren’t the best for desktops/laptops.
Historically, desktop applications would also be versions behind, but Flatpak really helps with this.
At this point, Debian is probably fine as a distro for a few year old computer that won’t be helped by fractional scaling. Pick a DE and install applications from Flathub.

This is needed. Servers need it, and it would be a nice feature to enable for personal systems. We would need to be able to build our own images with our own keys to really make this worthwhile. Especially with programs in my bin dir I’ve compiled or downloaded.
Do I trust Lennart to not do something asinine to turn this into a shit show? I do not. This would be better if it was someone who has security experience and system design cred.
